VBox 5.2.14 - "entitlement error" Installing VBox_GAs

Post by genjar » 2018/07/13 16:29:13

Hello,
Newbie here.
I don't know if I placed enough info in the Subject.
  • CentOS 7.5.1804 in
  • VBoxGuestAdditions.iso 5.2.14.123301 on
  • Win8.1 PC
I was trying to install VBox Guest Additions.
When I run this command

Code: Select all

yum install kernel-devel
from this site
https://www.megajason.com/2017/06/10/in ... -centos-7/

I get this error

I learned this command

Code: Select all

yum install kernel-devel-3.10.0-862.6.3.el7.x86_64
and no more errors.

A tech on another site stated "entitlement server...subscription-manager" error was displayed because I was trying to load a CentOS package(?) onto RHEL. However, I'm not using RHEL.

My question is why would I be receiving this error mentioning subscription-manager if I am using CentOS 7? And is there a link explaining this?

Thanks and God bless,
Genesius

I've tested all the links in your post that you get a 401 error on and I can access them all from here. My best guess is that you are behind a web proxy and the 401 error is coming from the proxy to tell you that you need to supply proxy username/password to get to the outside world.

You get the error about the entitlement server because you have installed the subscription-manager package.

Thanks for the quick reply TrevorH.
I think I might have found the answer.

Both on CentOS wiki
https://wiki.centos.org/HowTos/Virtuali ... entOSguest
and a 3rd party video
https://www.google.com/search?source=hp ... #kpvalbx=1
state to use Linux as Type and Red Hat/Red Hat (64 bit) as Version when installing CentOS on VBox.

Is it possible that VBox is installing a plugin, subscription-manager, and others, to be used by CentOS when it shouldn't?

The subscription manager error is entirely cosmetic and affects nothing. The problem is that you are getting 401 errors from the requests that yum makes using curl to obtain the necessary metadata to run.

TervorH,

The 401 went away when I used

Code: Select all

yum install kernel-devel-3.10.0-862.6.3.el7.x86_64
instead of

Code: Select all

yum install kernel-devel
Now a colleague is informing me that I need to "loop mount" the iso. Then I won't need to add the "-3.10.0-862.6.3.el7.x86_64" when I perform yum installs.

Off to Google.

Enjoy your weekend.

Thanks and God bless,
Genesius

Your colleague is incorrect. You only need to loopback mount the iso if you have no access to the internet to get to the CentOS mirror network. The iso will not contain the 862.6.3 kernel in any case as that was one released after the iso was spun.
